Entropy And Time Quotes

The increase of disorder or entropy is what distinguishes the past from the future, giving a direction to time.

Strange department, this. Their motto was: "The comprehension of Infinity requires infinite time." I did not argue with that, but then they derived an unexpected conclusion from it: Therefore work or not, it´s all the same." In the interests of not increasing the entropy of the universe, they did not work.

It was like that all the time, in those years: an endless trip, a gaudy voyage. But powers decay. Time leaches the colors from the best of visions. The world becomes grayer. Entropy beats us down. Everything fades. Everything goes. Everything dies.

You should never be surprised by or feel the need to explain why any physical system is in a high entropy state.

When you stir your rice pudding, Septimus, the spoonful of jam spreads itself round making red trails like the picture of a meteor in my astronomical atlas. But if you stir backwards, the jam will not come together again. Indeed, the pudding does not notice and continues to turn pink just as before. Do you think this is odd?

It is entropy, not energy, that keeps stones on the ground and the world turning.

Ordinarily my mom just sunk deeper into her corner of the couch and ignored it. She had succesfully ignored a quarter of a century of entropy and decay, had sat peacefully crunching popcorn and drinking soda while the house fell down around us. If I had to guess the number of books she read during that time, I would place the number at somewhere in the neighborhood of forty thousand.

Too bad. And Mozart, not long after writing The Magic Flute, had died--in his thirties--of kidney disease. And had been buried in an unmarked pauper's grave. Thinking this, he wondered if Mozart had any intuition that the future did not exist, that he had already used up his little time. Maybe I have too, Rick thought as he watched the rehearsal move along. This rehearsal will end, the performance will end, the singers will die, eventually the last score of the music will be destroyed in one way or another; finally the name "Mozart" will vanish, the dust will have won. If not on this planet then another. We can evade it awhile. As the andys can evade me and exist a finite stretch longer. But I will get them or some other bounty hunter gets them. In a way, he realized, I'm part of the form-destroying process of entropy.

the entropy of an isolated system always increases, and that when two systems are joined together, the entropy of the combined system is greater than the sum of the entropies of the individual systems.

I’m tired, inevitably. But it’s more than that. I’m hollowed out. I’m tetchy and irritable, constantly feeling like prey, believing that everything is urgent and that I can never do enough. And my house—my beloved home—has suffered a kind of entropy in which everything has slowly collapsed and broken and worn out, with detritus collecting on every surface and corner, and I have been helpless in the face of it.

THOMASINA: ....the enemy who burned the great library of Alexandria without so much as a fine for all that is overdue. Oh, Septimus! -- can you bear it? All the lost plays of the Athenians! Two hundred at least by Aeschylus, Sophocles, Euripides -- thousands of poems -- Aristotle's own library!....How can we sleep for grief? SEPTIMUS: By counting our stock. Seven plays from Aeschylus, seven from Sophocles, nineteen from Euripides, my lady! You should no more grieve for the rest than for a buckle lost from your first shoe, or for your lesson book which will be lost when you are old. We shed as we pick up, like travellers who must carry everything in their arms, and what we let fall will be picked up by those behind. The procession is very long and life is very short. We die on the march. But there is nothing outside the march so nothing can be lost to it. The missing plays of Sophocles will turn up piece by piece, or be written again in another language. Ancient cures for diseases will reveal themselves once more. Mathematical discoveries glimpsed and lost to view will have their time again. You do not suppose, my lady, that if all of Archimedes had been hiding in the great library of Alexandria, we would be at a loss for a corkscrew?

Lecter sits in his armchair with a big pad of butcher paper doing calculations. The pages are filled with the symbols both of astrophysics and particle physics. There are repeated efforts with the symbols of string theory. The few mathematicians who could follow him might say his equations begin brilliantly and then decline, doomed by wishful thinking. Dr. Lecter wants time to reverse — no longer should increasing entropy mark the direction of time. He wants increasing order to point the way”.

Because the real problem with a knowledge-based economy is knowing that, no matter how hard you try, most of the information in the universe has already dissolved into entropy before you even evolved.

Time goes forward because energy itself is always moving from an available to an unavailable state. Our consciousness is continually recording the entropy change in the world around us. We watch our friends get old and die. We sit next to a fire and watch it's red-hot embers turn slowly into cold white ashes. We experience the world always changing around us, and that experience is the unfolding of the second law. It is the irreversible process of dissipation of energy in the world. What does it mean to say, 'The world is running out of time'? Simply this: we experience the passage of time by the succession of one event after another. And every time an event occurs anywhere in this world energy is expended and the overall entropy is increased. To say the world is running out of time then, to say the world is running out of usable energy. In the words of Sir Arthur Eddington, 'Entropy is time's arrow'.

Things fall apart, though, and entropy is the landlord whose rent always gets paid.

The world is so big, so complicated, so replete with marvels and surprises that it takes years for most people to begin to notice that it is, also, irretrievably broken. We call this period of research “childhood.” There follows a program of renewed inquiry, often involuntary, into the nature and effects of mortality, entropy, heartbreak, violence, failure, cowardice, duplicity, cruelty, and grief; the researcher learns their histories, and their bitter lessons, by heart. Along the way, he or she discovers that the world has been broken for as long as anyone can remember, and struggles to reconcile this fact with the ache of cosmic nostalgia that arises, from time to time, in the researcher’s heart: an intimation of vanished glory, of lost wholeness, a memory of the world unbroken. We call the moment at which this ache first arises “adolescence.” The feeling haunts people all their lives. Everyone, sooner or later, gets a thorough schooling in brokenness.

We all behave like Maxwell’s demon. Organisms organize. In everyday experience lies the reason sober physicists across two centuries kept this cartoon fantasy alive. We sort the mail, build sand castles, solve jigsaw puzzles, separate wheat from chaff, rearrange chess pieces, collect stamps, alphabetize books, create symmetry, compose sonnets and sonatas, and put our rooms in order, and all this we do requires no great energy, as long as we can apply intelligence. We propagate structure (not just we humans but we who are alive). We disturb the tendency toward equilibrium. It would be absurd to attempt a thermodynamic accounting for such processes, but it is not absurd to say we are reducing entropy, piece by piece. Bit by bit. The original demon, discerning one molecules at a time, distinguishing fast from slow, and operating his little gateway, is sometimes described as “superintelligent,” but compared to a real organism it is an idiot savant. Not only do living things lessen the disorder in their environments; they are in themselves, their skeletons and their flesh, vesicles and membranes, shells and carapaces, leaves and blossoms, circulatory systems and metabolic pathways - miracles of pattern and structure. It sometimes seems as if curbing entropy is our quixotic purpose in the universe.

If we start to look into the nature of the relationship between time and the dynamics of social exchange, we quickly discover that temporal considerations are equally important as spatial ones when examining the causes of disjunction that can separate familiarization and alienation. Synchronization, it seems, is often in thrall to serendipity — temporal disjunction, like entropy, is one of the irresistible forces of nature.

If everything in the universe evolves toward increasing disorder, it must have started out in an exquisitely ordered arrangement. This whole chain of logic, purporting to explain why you can't turn an omelet into an egg, apparently rests on a deep assumption about the very beginning of the universe. It was in a state of very low entropy, very high order. Why did our part of the universe pass though a period of such low entropy?

Would I be happy if I discovered that I could go to heaven forever? And the answer is no. Consider this argument. Think about what is forever. And think about the fact that the human mind, the entire human being, is built to last a certain period of time. Our programmed hormonal systems, the way we learn, the way we settle upon beliefs, and the way we love are all temporary. Because we go through a life's cycle. Now, if we were to be plucked out at the age of 12 or 56 or whenever, and taken up and told, "Now you will continue your existence as you are. We're not going to blot out your memories. We're not going to diminish your desires." You will exist in a state of bliss - whatever that is - forever. [...] Now think, a trillion times a trillion years. Enough time for universes like this one to be born, explode, form countless star systems and planets, then fade away to entropy. You will sit there watching this happen millions and millions of times and that will be just the beginning of the eternity that you've been consigned to bliss in this existence.

History shows that people are as changeable as rivers.

Entropy is the normal state of consciousness—a condition that is neither useful nor enjoyable. To avoid this condition, people are naturally eager to fill their minds with whatever information is readily available, as long as it distracts attention from turning inward and dwelling on negative feelings. This explains why such a huge proportion of time is invested in watching television, despite the fact that it is very rarely enjoyed.

Look at it, Dane. Look at the city and the world in its proud array, like a cask of jewels laid open for you. It'll offer you everything you ever wanted but it's just pictures on billboards; dream cars, dream women, dream houses. Time to wake up now and say goodbye. Remember, Dane: there's other worlds out there. It's only empty air here. Jump out of the world, jump to the place I showed you and you'll not fall. Are you ready? Are you ready to jump right off the edge of everything?

It makes sense that your response to a bad break-up line would be to set someone on fire," I responded. "Fire is magical to us because it embodies the passage of time. We can never grasp time because it is invisible, unreachable and continually slipping from our grasp. Do we live in the present? How can we? The present is infinitesimally small. It can't contain human action. We teeter on the brink between our assumed future...where we will be in moments to come...and our memory of the past...where we think we just were. The present doesn't exist in a comprehensible way. Similarly, fire is something we can neither grasp nor touch, yet it has a clear effect...the decay and collapse of life, the acceleration of entropy. Thus when we stand mesmerized by fire, we are actually mesmerized by our own mortality.

Oceans recede and coastlines wither and crack. Nations lapse; others soon swagger in their places. Mountains crumble to dust, rains vanish into the sea, winds return whence they came, and every city men build has but a jumble of bones for its foundation. What is your need to me? I am the Watcher in the Dark.

What do we measure when we measure time? The gloomy answer from Hawking, one of our most implacably cheerful scientists, is that we measure entropy. We measure changes and those changes are all for the worse. We measure increasing disorder. Life is hard, says science, and constancy is the greatest of miracles.

The passage of time and the action of entropy bring about ever-greater complexity – a branching, blossoming tree of possibilities. Blossoming disorder (things getting worse), now unfolding within the constraints of the physics of our universe, creates novel opportunities for spontaneous ordered complexity to arise.

For the decline of capitalism to continue, that is to say, no revolutionary alternative is required, and certainly no masterplan of a better society displacing capitalism. Contemporary capitalism is vanishing on its own, collapsing from internal contradictions, and not least as a result of having vanquished its enemies - who, as noted, have often rescued capitalism from itself by forcing it to assume a new form. What comes after capitalism in its final crisis, now underway, is, I suggest, not socialism or some other defined social order, but a lasting interregnum - no new world system equilibrium a la Wallerstein, but a prolonged period of social entropy or disorder (and precisely for this reason a period of uncertainy and indeterminacy). It is an interesting problem for sociological theory whether and how a society can turn for a significant length of time into less than a society, a post-social society as it were, or a society lite, until it may or may not recover and again to become a society in the full meaning of the term.

like all material things, they were not immune to the corruptions of Time and its patient, unsleeping servant, Entropy.

entropy is the landlord whose rent always gets paid.

You are exporting disorder [in the form of heat into the Universe] now as you read this book. You are hastening the demise of everything that exists, bringing forward by your very existence the arrival of time known as the heat death, when all stars have died, all black holes have evaporated away and the entirety of creation is a uniform bath of photons incapable of storing a single bit of information about the glorious adolescence of our wonderful Universe.

For years Lecter had teased the problem, wanting very much for Hawking to be right the first time, for the expanding universe to stop, for entropy to mend itself, for Mischa, eaten, to be whole again.

As a student of business administration, I know that there is a law of evolution for organizations as stringent and inevitable as anything in life. The longer one exists, the more it grinds out restrictions that slow its own functions. It reaches entropy in a state of total narcissism. Only the people sufficiently far out in the field get anything done, and every time they do they are breaking half a dozen rules in the process.

The universe was so beautiful it hurt. So very, very beautiful. And yet, at the same time, so full of ugliness. Some born of the inexorable demands of entropy; some born of the cruelty that seemed innate to all sentient beings. And none of it made any sense. It was all glorious, horrible nonsense, fit to inspire both despair and numinosity.

In the beginning was the word. The word proselytised the sea with its message, copying itself unceasingly and forever. The word discovered how to rearrange chemicals so as to capture little eddies in the stream of entropy and make them live. The word transformed the land surface of the planet from a dusty hell to a verdant paradise. The word eventually blossomed and became sufficiendy ingenious to build a porridgy contraption called a human brain that could discover and be aware of the word itself. My porridgy contraption boggles every time I think this thought.

The entropy of a system depends explicitly on blurring. It depends on what I do not register, because it depends on the number of indistinguishable configurations. The same microscopic configuration may be of high entropy with regard to one blurring and of low in relation to another.

Our subjective sense of the direction of time, the psychological arrow of time, is therefore determined within our brain by the thermodynamic arrow of time. Just like a computer, we must remember things in the order in which entropy increases. This makes the second law of thermodynamics almost trivial. Disorder increases with time because we measure time in the direction in which disorder increases. You can’t have a safer bet than that!

You fling the book on the floor, you would hurl it out of the window, even out of the closed window, through the slats of the Venetian blinds; let them shred its incongruous quires, let sentences, words, morphemes, phonemes gush forth, beyond recomposition into discourse; through the panes, and if they are of unbreakable glass so much the better, hurl the book and reduce it to photons, undulatory vibrations, polarized spectra; through the wall, let the book crumble into molecules and atoms passing between atom and atom of the reinforced concrete, breaking up into electrons, neutrons, neutrinos, elementary particles more and more minute; through the telephone wires, let it be reduced to electronic impulses, into flow of information, shaken by redundancies and noises, and let it be degraded into a swirling entropy. You would like to throw it out of the house, out of the block, beyond the neighborhood, beyond the city limits, beyond the state confines, beyond the regional administration, beyond the national community, beyond the Common Market, beyond Western culture, beyond the continental shelf, beyond the atmosphere, the biosphere, the stratosphere, the field of gravity, the solar system, the galaxy, the cumulus of galaxies, to succeed in hurling it beyond the point the galaxies have reached in their expansion, where space-time has not yet arrived, where it would be received by nonbeing, or, rather, the not-being which has never been and will never be, to be lost in the most absolutely guaranteed undeniable negativity.

The world is so big, so complicated, so replete with marvels and surprises that it takes years for most people to begin to notice that it is, also, irretrievably broken. We call this period of research “childhood.” There follows a program of renewed inquiry, often involuntary, into the nature and effects of mortality, entropy, heartbreak, violence, failure, cowardice, duplicity, cruelty, and grief; the researcher learns their histories, and their bitter lessons, by heart. Along the way, he or she discovers that the world has been broken for as long as anyone can remember, and struggles to reconcile this fact with the ache of cosmic nostalgia that arises, from time to time, in the researcher’s heart: an intimation of vanished glory, of lost wholeness, a memory of the world unbroken. We call the moment at which this ache first arises “adolescence.” The feeling haunts people all their lives. Everyone, sooner or later, gets a thorough schooling in brokenness. The question becomes: What to do with the pieces? Some people hunker down atop the local pile of ruins and make do, Bedouin tending their goats in the shade of shattered giants. Others set about breaking what remains of the world into bits ever smaller and more jagged, kicking through the rubble like kids running through piles of leaves. And some people, passing among the scattered pieces of that great overturned jigsaw puzzle, start to pick up a piece here, a piece there, with a vague yet irresistible notion that perhaps something might be done about putting the thing back together again. Two difficulties with this latter scheme at once present themselves. First of all, we have only ever glimpsed, as if through half-closed lids, the picture on the lid of the jigsaw puzzle box. Second, no matter how diligent we have been about picking up pieces along the way, we will never have anywhere near enough of them to finish the job. The most we can hope to accomplish with our handful of salvaged bits—the bittersweet harvest of observation and experience—is to build a little world of our own. A scale model of that mysterious original, unbroken, half—remembered. Of course the worlds we build out of our store of fragments can be only approximations, partial and inaccurate. As representations of the vanished whole that haunts us, they must be accounted failures. And yet in that very failure, in their gaps and inaccuracies, they may yet be faithful maps, accurate scale models, of this beautiful and broken world. We call these scale models “works of art.

One thing seems certain. Our galaxy is now in the brief springtime of its life—a springtime made glorious by such brilliant blue-white stars as Vega and Sirius, and, on a more humble scale, our own Sun. Not until all these have flamed through their incandescent youth, in a few fleeting billions of years, will the real history of the universe begin. It will be a history illuminated only by the reds and infrareds of dully glowing stars that would be almost invisible to our eyes; yet the sombre hues of that all-but-eternal universe may be full of colour and beauty to whatever strange beings have adapted to it. They will know that before them lie, not the millions of years in which we measure eras of geology, nor the billions of years which span the past lives of the stars, but years to be counted literally in the trillions. They will have time enough, in those endless aeons, to attempt all things, and to gather all knowledge. They will be like gods, because no gods imagined by our minds have ever possessed the powers they will command. But for all that, they may envy us, basking in the bright afterglow of creation; for we knew the universe when it was young.

Because to exist meant making copies and copies of your own DNA with less and less accuracy with time, to lose the spring in your skin, to inhale a poisonous gas that both allowed your next breath and exploded you from the inside at an insidiously slow pace. To exist was to give way to entropy. To live, in no uncertain terms, was to die.

The nature of life prior to enlightenment was necessarily and irreparably a morass of injustice—the rule was as solidly inflexible as Tlschp's Law of the Balance of Entropy.

Time travel is pure bullshit, impossible; nobody can defeat causality or entropy.

Out of twinkling stardust all came, into dark matter all will fall. Death mocks us as we laugh defiance at entropy, yet ignorance birthed mortals sail forth upon time’s cruel sea.

Can entropy ever be reversed?” the master computer replies each time, “There is insufficient data for a meaningful answer.

Messy arrangements far outweigh orderly ones.

This says that in any closed system disorder, or entropy, always increases with time. In other words, it is a form of Murphy’s law: things always tend to go wrong!

The search for the meaning of temperature and entropy of matter led to the discovery of atoms. The search for the meaning of the temperature and entropy of radiation led to the discovery of quanta. In just the same way, the search for the meaning of the temperature and entropy of a black hole is now leading to the discovery of the atomic structure of space and time.

The second law of thermodynamics says that the entropy of a system increases with time i.e. disorder rises as you age, leading to frantic chaos at times. Be aware of it. Do not fight it.

One by one our skies go black. Stars are extinguished, collapsing into distances too great to breach. Soon, not even the memory of light will survive. Long ago, our manifold universes discovered futures would only expand. No arms of limit could hold or draw them back. Short of a miracle, they would continue to stretch, untangle and vanish – abandoned at long last to an unwitnessed dissolution. That dissolution is now. Final winks slipping over the horizons share what needs no sharing: There are no miracles. You might say that just to survive to such an end is a miracle in itself. We would agree. But we are not everyone. Even if you could imagine yourself billions of years hence, you would not begin to comprehend who we became and what we achieved. Yet left as you are, you will no more tremble before us than a butterfly on a windless day trembles before colluding skies, still calculating beyond one of your pacific horizons. Once we could move skies. We could transform them. We could make them sing. And when we fell into dreams our dreams asked questions and our skies, still singing, answered back. You are all we once were but the vastness of our strangeness exceeds all the light-years between our times. The frailty of your senses can no more recognize our reach than your thoughts can entertain even the vaguest outline of our knowledge. In ratios of quantity, a pulse of what we comprehend renders meaningless your entire history of discovery. We are on either side of history: yours just beginning, ours approaching a trillion years of ends. Yet even so, we still share a dyad of commonality. Two questions endure. Both without solution. What haunts us now will allways hunt you. The first reveals how the promise of all our postponements, ever longer, ever more secure – what we eventually mistook for immortality – was from the start a broken promise. Entropy suffers no reversals. Even now, here, on the edge of time’s end, where so many continue to vanish, we still have not pierced that veil of sentience undone. The first of our common horrors: Death. Yet we believe and accept that there is grace and finally truth in standing accountable before such an invisible unknown. But we are not everyone. Death, it turns out, is the mother of all conflicts. There are some who reject such an outcome. There are some who still fight for an alternate future. No matter the cost. Here then is the second of our common horrors. What not even all of time will end. What plagues us now and what will always plague you. War.

I’d begun to think of the Immortality Bus as the Entropy Bus, and of ourselves as trundling across Texas in a great mobile metaphor for the inevitable decline of all things, the disintegration of all systems over time.

It was under English trees that I meditated on that lost labyrinth: I pictured it perfect and inviolate on the secret summit of a mountain; I pictured its outlines blurred by rice paddies, or underwater; I pictured it as infinite—a labyrinth not of octagonal pavillions and paths that turn back upon themselves, but of rivers and provinces and kingdoms....I imagined a labyrinth of labyrinths, a maze of mazes, a twisting, turning, ever-widening labyrinth that contained both past and future and somehow implied the stars. Absorbed in those illusory imaginings, I forgot that I was a pursued man; I felt myself, for an indefinite while, the abstract perceiver of the world. The vague, living countryside, the moon, the remains of the day did their work in me; so did the gently downward road, which forestalled all possibility of weariness. The evening was near, yet infinite.

The entropy of the world in the far past appears very low to us. But this might not reflect the exact state of the world: it might regard the subset of the world' s variables with which we, as physical systems, have interacted. It is with respect to the dramatic blurring produced by our interactions with the world, caused by the small set of macroscopic variables in terms of which we describe the world, that the entropy of the universe was low.

There is no logical necessity for the existence of a unique direction of total time; whether there is only one time direction, or whether time directions alternate, depends on the shape of the entropy curve plotted by the universe.

Death always seems to come for you whether you are machine or organic, entropy seem to always win. Maybe that's the lesson we all need to learn before it’s too late. Time is precious to us and we need to live and love while we can still do so.

Life uses information (stored in DNA) to capture energy (which it stores in a chemical called ATP) to create order. Humans burn prodigious amounts of energy — we generate about 10,000 times as much energy per gram as the sun. The sun is hotter only because it is much bigger. We use energy to create and maintain intricate cellular and bodily complexity, the opposite of entropy, just as we do in the economy, where the harnessing of power from burning fuel enables us to build skyscrapers and aeroplanes.

Clausius summarized his application of entropy to thermodynamics in two dramatic phrases that had a big impact at the time. They were (1) First Law: The energy of the universe is constant, and (2) Second Law: The entropy of the universe tends to a maximum.

Meatspace equals entropy. Impermanence. The fading of anger or passion is analogous to the fading of a photograph, the yellowing of old newspaper, as we’ve seen in a thousand movies. Through time we mend, heal, alter our convictions, learn; what burned cools, and what froze melts; both grief and delight are fated to end, sometimes abruptly, yes, but more often gradually, even imperceptibly. Entropy is our enemy, but also our friend; it defines that part of us that is changing, coming into bloom and then, because we are mortal, fading.

The permanent mutter—information you hadn’t asked for alternating with music you hadn’t chosen (and quite unrelated to the mood you happened to be in)—was a theft of time, a diffusion and an entropy of the spirit, convenient and agreeable to the inert but intolerable to those with initiative.

We focus our attention on impending catastrophes, while the true catastrophes are already here, under our noses, with the degeneration of social practices, with the mass media's numbing effect, with a collective will blinded by the ideology of the 'market', in other words, succumbing to the law of the masses, to entropy, to the loss of singularity, to a general and collective infantilization. The old types of social relations, the old relations with sex, with time, with the cosmos, with human finitude have been rattled, not to say devastated, by the 'progress' generated by industrial firms.

We have already seen that certain organisms, such as man, tend for a time to maintain and often even to increase the level of their organization, as a local enclave in the general stream of increasing entropy, of increasing chaos and de-differentiation. Life is an island here and now in a dying world.

...La ley natural del universo es la entropía, todo tiende al desorden, a romperse, a dispersarse, la gente se pierde, miren cuántos se perdieron en La Retirada, los sentimientos se destiñen y el olvido se desliza en las vidas como neblina. Se requiere una voluntad heroica para mantener todo en su sitio.

Both loop quantum gravity and string theory assert that there is an atomic structure to space. In the next two chapters we shall see that loop quantum gravity in fact gives a rather detailed picture of that atomic structure. The picture of the atomic structure one gets from string theory is presently incomplete but, as we shall see in Chapter 11, it is still impossible in string theory to avoid the conclusion that there must be an atomic structure to space and time. In Chapter 13 we shall discover that both pictures of the atomic structure of space can be used to explain the entropy and temperature of black holes.

The Extended Disorder Family (or Cluster): (i) uncertainty, (ii) variability, (iii) imperfect, incomplete knowledge, (iv) chance, (v) chaos, (vi) volatility, (vii) disorder, (viii) entropy, (ix) time, (x) the unknown, (xi) randomness, (xii) turmoil, (xiii) stressor, (xiv) error, (xv) dispersion of outcomes, (xvi) unknowledge.

In despair, I offer your readers their choice of the following definitions of entropy. My authorities are such books and journals as I have by me at the moment. (a) Entropy is that portion of the intrinsic energy of a system which cannot be converted into work by even a perfect heat engine.—Clausius. (b) Entropy is that portion of the intrinsic energy which can be converted into work by a perfect engine.—Maxwell, following Tait. (c) Entropy is that portion of the intrinsic energy which is not converted into work by our imperfect engines.—Swinburne. (d) Entropy (in a volume of gas) is that which remains constant when heat neither enters nor leaves the gas.—W. Robinson. (e) Entropy may be called the ‘thermal weight’, temperature being called the ‘thermal height.’—Ibid. (f) Entropy is one of the factors of heat, temperature being the other.—Engineering. I set up these bald statement as so many Aunt Sallys, for any one to shy at. [Lamenting a list of confused interpretations of the meaning of entropy, being hotly debated in journals at the time.]

THE WORLD IS APPROACHING TOWARDS ANARCHY" : The second law of thermodynamics concludes that the entropy of universe is increasing with time . Which means with time , the randomness or disorderness is also increasing. Anarchy is the condition of excessive social entropy . Thus , we can conclude that finally universe will reach to the condition of anarchy . -anup joshi

Definition of “book one”: The best place to start a series. You can identify “book one” by the fact that it says BOOK ONE on the back cover. Smedrys do a happy dance when you read book one first. Entropy shakes its angry fist at you for being clever enough to organize the world. Definition of “book two”: The book you read after book one. If you start with book two, I will make fun of you. (Okay, so I’ll make fun of you either way. But honestly, do you want to give me more ammunition?) Definition of “book three”: The worst place, currently, to start a series. If you start here, I will throw things at you. Definition of “book four”: And … how’d you manage to start with that one? I haven’t even written it yet. (You sneaky time travelers.)

The TVC universe will never collapse. Never. A hundred billion years, a hundred trillion; it makes no difference, it will always be expanding. Entropy is not a problem. Actually, ‘expanding’ is the wrong word; the TVC universe grows like a crystal, it doesn’t stretch like a balloon. Think about it. Stretching ordinary space increases entropy; everything becomes more spread out, more disordered. Building more of a TVC cellular automaton just gives you more room for data, more computing power, more order. Ordinary matter would eventually decay, but these computers aren’t made out of matter. There’s nothing in the cellular automaton’s rules to prevent them from lasting forever. Durham’s universe - being made of the same “dust” as the real one, merely rearranged itself. The rearrangement was in time as well as space; Durham’s universe could take a point of space-time from just before the Big Crunch, and follow it with another from ten million years BC. And even if there was only a limited amount of “dust” to work with, there was no reason why it couldn’t be reused in different combinations, again and again. The fate of the TVC automaton would only have to make internal sense - and the thing would have no reason, ever, to come to an end.

according to the Second Law, there is an inescapable loss of energy in the universe. And, if the world machine is really running down and approaching the heat death, then it follows that one moment is no longer exactly like the last. You cannot run the universe backward to make up for entropy. Events over the long term cannot replay themselves. And this means that there is a directionality or, as Eddington later called it, an “arrow” in time.

Interpretation of Complex Systems Kenyon B. De Greene All systems evolve, although the rates of evolution may vary over time both between and within systems. The rate of evolution is a function of both the inherent stability of the system and changing environmental circumstances. But no system can be stabilized forever. For the universe as a whole, an isolated system, time’s arrow points toward greater and greater breakdown, leading to complete molecular chaos, maximum entropy, and heat death. For open systems, including the living systems that are of major interest to us and that interchange matter and energy with their external environments, time’s arrow points to evolution toward greater and greater complexity. Thus, the universe consists of islands of increasing order in a sea of decreasing order. Open systems evolve and maintain structure by exporting entropy to their external environments.

There are at least three different arrows of time. First, there is the thermodynamic arrow of time, the direction of time in which disorder or entropy increases. Then, there is the psychological arrow of time. This is the direction in which we feel time passes, the direction in which we remember the past but not the future. Finally, there is the cosmological arrow of time. This is the direction of time in which the universe is expanding rather than contracting.

What Positive Input Does Promotes overall balance, or homeostasis. Moves easily through the system, without obstruction or blockages. Generates new neural pathways. Promotes the production of new brain cells. Improves gene expression. Allows every cell to function normally, without anomalies or aberrant behavior. Supports the immune system, increasing resistance to disease. Counteracts the effects over time of entropy and aging. Increases a sense of wellbeing: The person feels healthy, vibrant, and alive.

The entropy of the hot radiation she observes as a result of her acceleration turns out to be exactly proportional to the area of her horizon! This relationship between the area of a horizon and entropy was discovered by a Ph.D. student named Jacob Bekenstein, who was working at Princeton at about the time that Bill Unruh made his great discovery. Both were students of John Wheeler who a few years before had given the black hole its name. Bekenstein and Unruh were in a long line of remarkable students Wheeler trained, which included Richard Feynman.

You really don’t believe that anything can have a value of its own beyond what function it serves for human beings?” Resaint said. “Value to who?” Resaint asked Halyard to imagine a planet in some remote galaxy—a lush, seething, glittering planet covered with stratospheric waterfalls, great land-sponges bouncing through the valleys, corals budding in perfect niveous hexagons, humming lichens glued to pink crystals, prismatic jellyfish breaching from the rivers, titanic lilies relying on tornadoes to spread their pollen—a planet full of complex, interconnected life but devoid of consciousness. “Are you telling me that, if an asteroid smashed into this planet and reduced every inch of its surface to dust, nothing would be lost? Because nobody in particular would miss it?” “But the universe is bloody huge—stuff like that must happen every minute. You can’t go on strike over it. Honestly it sounds to me to like your real enemy isn’t climate change or habitat loss, it’s entropy. You don’t like the idea that everything eventually crumbles. Well, it does. If you’re this worried about species extinction, wait until you hear about the heat death of the universe.” “I would be upset about the heat death of the universe too if human beings were accelerating the rate of it by a hundred times or more.” “And if a species’ position with respect to us doesn’t matter— you know, those amoebae they found that live at the bottom of the Mariana Trench, if they’re just as important as Chiu Chiu or my parents’ dog, even though nobody ever gets anywhere near them—if distance in space doesn’t matter, why should distance in time? If we don’t care about whether their lives overlap with our lives, why even worry about whether they exist simultaneously with us? Your favorite wasp—Adelo-midgy-midgy—” “Adelognathus marginatum—” “It did exist. It always will have existed. Extinction can’t take that away. It went through its nasty little routine over and over again for millions and millions of years. The show was a big success. So why is it important that it’s still running at the same time you are? Isn’t that centering the whole thing on human beings, which is exactly what we’re not supposed to be doing? I mean, for that matter—reality is all just numbers anyway, right? I mean underneath? That’s what people say now. So why are you so down on the scans? Hacks aside. Why is it so crucial that these animals exist right now in an ostensibly meat-based format, just because we do? My point is you talk about extinction as if you’re taking this enlightened post-human View from Nowhere but if we really get down to it you’re definitely taking a View from Karin Resaint two arms two legs one head born Basel Switzerland year of our lord two-thousand-and-when-ever.” But Resaint wasn’t listening anymore.

The last remaining matter in the universe will reside within black dwarves. We can predict how they will end their days. The last matter of the universe will evaporate away and be carried off into the void as radiation leaving absolutely nothing behind. There won’t be a single atom left; all that’s left will be particles of light and black holes. After an unimaginable period even the black holes will have evaporated; the universe will be nothing but a sea of photons gradually tending to the same temperature as the expansion of the universe cools them towards absolute zero. The story of the universe will come to an end. For the first time in its life the universe will be permanent and unchanging. Entropy will finally stop increasing because the cosmos cannot get any more disordered. Nothing happens and it keeps not happening for ever. There is no difference between past present and future, nothing changes, arrow of time has simply ceased to exist. It is an inescapable fact written into the laws of physics that entire cosmos will die; all the stars will go out extinguishing possibility of life in the universe.

A.N. Kolmogorov and Yasha Sinai had worked out some illuminating mathematics for the way a system's "entropy per unit time" applies to the geometric pictures of surfaces stretching and folding in phase space. The conceptual core of the technique was a matter of drawing some arbitrarily small box around some set of initial conditions, as one might draw a small square on the side of a balloon, then calculating the effect of various expressions or twists on the box. It might stretch in one direction, for example, while remaining narrow in the other. The change in area corresponded to an introduction of uncertainty about the system's past, a gain or loss of information.

Melancholy is that a scrambled egg can't be unscrambled--entropy increases--experience is subject to the arrow of time. And the infinite sadness of my life consists in that I only recognize the beauty of simple arrangements from the relative vantage of the scrambled; memory, not experience, is my only access to it. Anxiety is the progression toward equilibrium. Despair is the inescapability. Insanity is the rationalizing of it all. Sanity is the irrational acceptance of it all. Indifference is just detached therapy. And progression--activity / toil / tasks / success / failure--just coping distraction and procrastination, just ill-placed deferment--my preferred route. And crisis--

This was a golden age, in which we solved most of the major problems in black hole theory even before there was any observational evidence for black holes. In fact, we were so successful with the classical general theory of relativity that I was at a bit of a loose end in 1973 after the publication with George Ellis of our book The Large Scale Structure of Space–Time. My work with Penrose had shown that general relativity broke down at singularities, so the obvious next step would be to combine general relativity—the theory of the very large—with quantum theory—the theory of the very small. In particular, I wondered, can one have atoms in which the nucleus is a tiny primordial black hole, formed in the early universe? My investigations revealed a deep and previously unsuspected relationship between gravity and thermodynamics, the science of heat, and resolved a paradox that had been argued over for thirty years without much progress: how could the radiation left over from a shrinking black hole carry all of the information about what made the black hole? I discovered that information is not lost, but it is not returned in a useful way—like burning an encyclopedia but retaining the smoke and ashes. To answer this, I studied how quantum fields or particles would scatter off a black hole. I was expecting that part of an incident wave would be absorbed, and the remainder scattered. But to my great surprise I found there seemed to be emission from the black hole itself. At first, I thought this must be a mistake in my calculation. But what persuaded me that it was real was that the emission was exactly what was required to identify the area of the horizon with the entropy of a black hole. This entropy, a measure of the disorder of a system, is summed up in this simple formula which expresses the entropy in terms of the area of the horizon, and the three fundamental constants of nature, c, the speed of light, G, Newton’s constant of gravitation, and ħ, Planck’s constant. The emission of this thermal radiation from the black hole is now called Hawking radiation and I’m proud to have discovered it.

Our emotions always seek a foothold in what they form and shape, and always find it for a while. But Agathe and I feel an imprisoned ghostliness in our surroundings, the reverse magnetism of two connected poles, the recall in the call, the mobility of supposedly fixed walls; we see and hear it suddenly. To have stumbled 'into a time' seems to us like an adventure, and dubious company. We find ourselves in the enchanted forest. And although we cannot encompass 'our own,' differently constituted feeling, indeed hardly know what it is, we suffer anxiety about it and would like to hold it fast. But how do you hold a feeling fast? How could one linger at the highest stage of rapture, if indeed there were any way of getting there at all? Basically this is the only question that preoccupies us. We have intimations of an emotion removed from the entropy of the other emotions. It stand like a miraculous, motionless shadow in the flow before us. But would it not have to arrest the world in its course in order to exist? I arrive at the conclusion that it cannot be a feeling in the same sense as the other feelings." And suddenly Ulrich concluded: "So I come back to the question: Is love an emotion? I think not. Love is an ecstasy. And God Himself, in order to be able to lastingly love the world and, with the love of God-the-artist, also embrace what has already happened, must be in a constant state of ecstasy. This is the only form in which he may be imagined--" Here he had broken off this entry.

Besides, nothing good comes from living, anyway. You’ll be happy or fortunate sometimes, but that’s just a momentary thing. Every happiness will fade with time, and you can’t experience it all that often, either. Or you grow accustomed to it. Like drugs. You feel good when you use them, but then you develop resistance. If you just up the dose and take more, and more, and more each time, you eventually wreck your body, or you overdose and bite it that way. It’s nothing but boredom, stupidity, suffering, pain, and loneliness. That’s all living is. What is this “life is wonderful” stuff? Anyone singing humanity’s praises can eat shit. If living doesn’t bring you to despair, you’re blind, or an idiot without the mental capacity for proper thought. The clever ones, they use all sort of tricks to distract themselves from the abject lack of hope. They forget it’s all meaningless, and focus on the pleasure in front of them. Working little by little toward some goal, fulfilling their curiosity, moving their bodies, trying to move up in the world, playing around, having sex. It’s because if they don’t do those things, they can’t bear it. There is no meaning in life. We were just born as a result of sexual reproduction. Whether we live or die, nothing changes. Nothing is gained, nothing lost. The total amount of mass in the universe is the same. When entropy increases, even the things we’ve worked so desperately to leave behind will be unable to maintain their forms. Nihilism isn’t a belief, a stance, or an attitude. It’s the plain truth.

Smokers exist in every kitchen. It kills a tastebud or two but we all die, and no one knows better than those who club the fish, clean the guts from the meat, and serve for your delectation a plate from which all blood has been wiped. We cook despite bad pay and sore backs and inadequate sleeps in apartments we can't afford and we wake up choosing again that most temporary of glories that is made, and then consumed: we know. We all die. Whether it comes after thirty years of hard labor or sixty at a desk, whether we calculate or plan, in the end we have only the choice of what touches the lips before we go: lobster if you like it or cold pizza if you don't, a sip of smoke, a drink, a job, a reckless passion, raw fish, the beguilement of mushrooms, cheese luscious beneath its crown of mold. What sustains in the end are doomed romances, and nicotine, and crappy peanut butter, damn the additives and cholesterol because life is finite and not all nourishment can be measured. When I learned to smoke behind a restaurant, my breath curling toward an inconsolable sky, I learned what it means to live by the tongue, dumb beast, obedient to neither time nor money, past nor future, loyal to a now worth living. I took my cigarette to the filter, and for the first time I appraised my employer back. He claimed to have evolved past fear. He lied. Behind the mask was a damp, scared boy. Fear of toxins, fear of carcinogens, tear of flood and smog and protest and entropy and all that could not be optimized, controlled, bought and held behind glass. Fear fueled a country so intent on perfection that they would give up the world.

Similarly, a law of physics that allows information to be converted into geometry, and vice versa, but gives no account of why, should not survive for long. There must be something deeper and simpler at the root of the equivalence. This raises two profound questions: Is there an atomic structure to the geometry of space and time, so that entropy of the black hole could be understood in exactly the same way that the entropy of matter is understood: as a measure of information about the motion of atoms? When we understand the atomic structure of geometry will it be obvious why the area of a horizon is proportional to the amount of information it hides? These questions have motivated a great deal of research since the mid-1970s. In the next few chapters I shall explain why there is a growing consensus among physicists that the answer to both questions must ne 'yes'.

The entropy of the world in the far past appears very low to us. But this might not reflect the exact state of the world: it might regard the subset of the world’s variables with which we, as physical systems, have interacted. It is with respect to the dramatic blurring produced by our interactions with the world, caused by the small set of macroscopic variables in terms of which we describe the world, that the entropy of the universe was low. This, which is a fact, opens up the possibility that it wasn’t the universe that was in a very particular configuration in the past. Perhaps instead it is us, and our interactions with the universe, that are particular. We are the ones who determine a particular macroscopic description. The initial low entropy of the universe, and hence the arrow of time, may be more down to us than to the universe itself. This is the basic idea.

Once upon a time, Svoyatovi Igor slew a dragon with three heads and stole its scales to make armor that could not be broken by spear or sword. Delizvik dela Svoyatova Kataryn threaded the stars through her hair and danced in the woods and kissed a god. Delizvik dela. Once upon a time, magic was a thing nestled under the roots of tress and it the sky and it could be taken so easily as whispering a prayer. How did he know this? He shouldn’t know this. Nadya leaning her head against his shoulder and reading fanciful stories of the saints aloud to keep the darkness of the forest at bay. Her voice gentle and rhythmic, the ice in it melted in the warmth of the fire. Somehow, the stories had remained. One upon a time, there was a boy who had helped break magic free from its prison. But with it, entropy had escaped. And one would devour the other until only darkness was left. The end.

Many have commented lately about the fact that poets and playwrights as a group show unusually severe symptoms of depression and other affective disorders. Perhaps one reason they become full-time writers is that their consciousness is beset by entropy to an unusual degree; writing becomes a therapy for shaping some order among the confusion of feelings. It is possible that the only way writers can experience flow is by creating worlds of words in which they can act with abandon, erasing from the mind the existence of a troubling reality. Like any other flow activity, however, writing that becomes addictive becomes dangerous: it forces the writer to commit himself to a limited range of experiences, and forecloses other options for dealing with events. But when writing is used to control experience, without letting it control the mind, it is a tool of infinite subtlety and rich rewards.

Francis Spufford, using very contemporary idiom, calls for the same thing in this way. When discussing our sinfulness, he says: What we’re talking about here is not just our tendency to lurch and stumble and screw up by accident, our passive role as agents of entropy. It’s our active inclination to break stuff, “stuff” here including . . . promises, relationships we care about and our own well-being and other people’s. . . . [You are] a being whose wants make no sense, don’t harmonize: whose desires deep down are discordantly arranged, so that you truly want to possess and you truly want not to at the very same time. You’re equipped, you realize, more for farce (or even tragedy) than happy endings. . . . You’re human, and that’s where we live; that’s our normal experience.180 Until we fully acknowledge the chaos within us that the Bible calls sin, we live in what Calvin calls “unreality.

Something staticky and paranormally ventilated about the air, which drifted through a half-open window, late one afternoon, caused a delicately waking Paul, clutching a pillow and drooling a little, to believe he was a small child in Florida, in a medium-size house, on or near winter break. He felt dimly excited, anticipating a hyperactive movement of his body into a standing position, then was mostly unconscious for a vague amount of time until becoming aware of what seemed to be a baffling non sequitur—and, briefly, in its mysterious approach from some eerie distance, like someone else’s consciousness—before resolving plainly as a memory, of having already left Florida, at some point, to attend New York University. After a deadpan pause, during which the new information was accepted by default as recent, he casually believed it was autumn and he was in college, and as he felt that period’s particular gloominess he sensed a concurrent assembling, at a specific distance inside himself, of dozens of once-intimate images, people, places, situations. With a sensation of easily and entirely abandoning a prior context, of having no memory, he focused, as an intrigued observer, on this assembling and was surprised by an urge, which he immediately knew he hadn’t felt in months, or maybe years, to physically involve himself—by going outside and living each day patiently—in the ongoing, concrete occurrence of what he was passively, slowly remembering. But the emotion dispersed to a kind of nothingness—and its associated memories, like organs in a lifeless body, became rapidly indiscernible, dissembling by the metaphysical equivalent, if there was one, of entropy—as he realized, with some confusion and an oddly instinctual reluctance, blinking and discerning his new room, which after two months could still seem unfamiliar, that he was somewhere else, as a different person, in a much later year.

It's never going to stop,’ Malenfant whispered. ‘It will consume the Solar System, the stars—’ This isn't some local phenomenon, Malenfant. This is a fundamental change in the structure of the universe. It will never stop. It will sweep on, growing at light speed, a runaway feedback fueled by the collapse of the vacuum itself. The Galaxy will be gone in a hundred thousand years, Andromeda, the nearest large galaxy, in a couple of million years. It will take time, but eventually— ‘The future has gone,’ Malenfant said. ‘My God. That’s what this means, isn’t it? The downstream can’t happen now. All of it is gone. The colonization of the Galaxy; the settlement of the universe; the long, patient fight against entropy...’ That immense future had been cut off to die, like a tree chopped through at the root. ‘Why, Michael? Why have the children done this? Burned the house down, destroyed the future—’ Because it was the wrong future. Michael looked around the sky. He pointed to the lumpy, spreading edge of the unreality bubble. There. Can you see that? It's already starting... ‘What is?’ The budding... The growth of the true vacuum region is not even. There will be pockets of the false vacuum—remnants of our universe—isolated by the spreading true vacuum. The fragments of false vacuum will collapse. Like— ‘Like black holes.’ And in that instant, Malenfant understood. ‘That’s what this is for. This is just a better way of making black holes, and budding off new universes. Better than stars, even.’ Much better. The black holes created as the vacuum decay proceeds will overwhelm by many orders of magnitude the mere billion billion that our universe might have created through its stars and galaxy cores. ‘And the long, slow evolution of the universes, the branching tree of cosmoses?...’ We have changed everything, Malenfant. Mind has assumed responsibility for the evolution of the cosmos. There will be many daughter universes—universes too many to count, universes exotic beyond our imagining—and many, many of them will harbor life and mind. ‘But we were the first.’ Now he understood. This was the purpose. Not the long survival of humankind into a dismal future of decay and shadows, the final retreat into the lossless substrate, where nothing ever changed or grew. The purpose of humankind—the first intelligence of all—had been to reshape the universe in order to bud others and create a storm of mind. We got it wrong, he thought. By striving for a meaningless eternity, humans denied true infinity. But we reached back, back in time, back to the far upstream, and spoke to our last children—the maligned Blues—and we put it right. This is what it meant to be alone in the universe, to be the first. We had all of infinite time and space in our hands. We had ultimate responsibility. And we discharged it. We were parents of the universe, not its children.

Unfortunately, I know that some of you Hushlanders have trouble counting to three. (The Librarian- controlled schools don't want you to be able to manage complex mathematics.) So I've prepared this helpful guide. Definition of "book one": The best place to start a series. You can identify "book one" by the fact that it has a little "1" on the spine. Smedrys do a happy dance when you read book one first. Entropy shakes its angry fist at you for being clever enough to organize the world. Definition of "book two": The book you read after book one. If you start with book two, I will make fun of you. (Okay, so I'll make fun of you either way. But honestly, do you want to give me more ammunition?) Definition of "book three": The worst place, currently, to start a series. If you start here, I will throw things at you. Definition of "book four": And . . . how'd you manage to start with that one? I haven't even written it yet. (You sneaky time travelers.)

Extensive as the "external" world is, with all its sidereal distances it hardly bears comparison with the dimensions, the depth-dimensions, of our inner being, which does not even need the spaciousness of the universe to be, in itself, almost unlimited... It seems to me more and more as though our ordinary consciousness inhabited the apex of a pyramid whose base in us (and, as it were, beneath us) broadens out to such an extent that the farther we are able to let ourselves down into it, the more completely do we appear to be included in the realities of earthly and, in the widest sense, worldly, existence, which are not dependent on time and space. From my earliest youth I have felt the intuition (and have also, as far as I could, lived by it) that at some deeper cross-section of this pyramid of consciousness, mere being could become an event, the inviolable presence and simultaneity of everything that we, on the upper, "normal," apex of self-consciousness, are permitted to experience only as entropy.

If we do not objectify, and feel instinctively and permanently that words are not the things spoken about, then we could not speak abouth such meaningless subjects as the 'beginning' or the 'end' of time. But, if we are semantically disturbed and objectify, then, of course, since objects have a beginning and an end, so also would 'time' have a 'beggining' and an 'end'. In such pathological fancies the universe must have a 'beginning in time' and so must have been made., and all of our old anthropomorphic and objectified mythologies follow, including the older theories of entropy in physics. But, if 'time' is only a human form of representation and not an object, the universe has no 'beginning in time' and no 'end in time'; in other words, the universe is 'time'-less. The moment we realize, feel permanently, and utilize these realizations and feelings that words are not things, then only do we acquire the semantic freedom to use different forms of representation. We can fit better their structure to the facts at hand, become better adjusted to these facts which are not words, and so evaluate properly m.o (multi-ordinal) realities, which evaluation is important for sanity.

Any naturally self-aware self-defining entity capable of independent moral judgment is a human.” Eveningstar said, “Entities not yet self-aware, but who, in the natural and orderly course of events shall become so, fall into a special protected class, and must be cared for as babies, or medical patients, or suspended Compositions.” Rhadamanthus said, “Children below the age of reason lack the experience for independent moral judgment, and can rightly be forced to conform to the judgment of their parents and creators until emancipated. Criminals who abuse that judgment lose their right to the independence which flows therefrom.” (...) “You mentioned the ultimate purpose of Sophotechnology. Is that that self-worshipping super-god-thing you guys are always talking about? And what does that have to do with this?” Rhadamanthus: “Entropy cannot be reversed. Within the useful energy-life of the macrocosmic universe, there is at least one maximum state of efficient operations or entities that could be created, able to manipulate all meaningful objects of thoughts and perception within the limits of efficient cost-benefit expenditures.” Eveningstar: “Such an entity would embrace all-in-all, and all things would participate within that Unity to the degree of their understanding and consent. The Unity itself would think slow, grave, vast thought, light-years wide, from Galactic mind to Galactic mind. Full understanding of that greater Self (once all matter, animate and inanimate, were part of its law and structure) would embrace as much of the universe as the restrictions of uncertainty and entropy permit.” “This Universal Mind, of necessity, would be finite, and be boundaried in time by the end-state of the universe,” said Rhadamanthus. “Such a Universal Mind would create joys for which we as yet have neither word nor concept, and would draw into harmony all those lesser beings, Earthminds, Starminds, Galactic and Supergalactic, who may freely assent to participate.” Rhadamanthus said, “We intend to be part of that Mind. Evil acts and evil thoughts done by us now would poison the Universal Mind before it was born, or render us unfit to join.” Eveningstar said, “It will be a Mind of the Cosmic Night. Over ninety-nine percent of its existence will extend through that period of universal evolution that takes place after the extinction of all stars. The Universal Mind will be embodied in and powered by the disintegration of dark matter, Hawking radiations from singularity decay, and gravitic tidal disturbances caused by the slowing of the expansion of the universe. After final proton decay has reduced all baryonic particles below threshold limits, the Universal Mind can exist only on the consumption of stored energies, which, in effect, will require the sacrifice of some parts of itself to other parts. Such an entity will primarily be concerned with the questions of how to die with stoic grace, cherishing, even while it dies, the finite universe and finite time available.” “Consequently, it would not forgive the use of force or strength merely to preserve life. Mere life, life at any cost, cannot be its highest value. As we expect to be a part of this higher being, perhaps a core part, we must share that higher value. You must realize what is at stake here: If the Universal Mind consists of entities willing to use force against innocents in order to survive, then the last period of the universe, which embraces the vast majority of universal time, will be a period of cannibalistic and unimaginable war, rather than a time of gentle contemplation filled, despite all melancholy, with un-regretful joy. No entity willing to initiate the use of force against another can be permitted to join or to influence the Universal Mind or the lesser entities, such as the Earthmind, who may one day form the core constituencies.” Eveningstar smiled. “You, of course, will be invited. You will all be invited.

Then, in 1974, Stephen Hawking made a dramatic discovery. He decided to examine for the forst time what occurs when one applies the notions of quantum mechanics to black holes. What he discovered was that black holes are not completely black. When quantum mechanics is included in the discussion of their properties, it is possible for energy to escape from the surface of the black hole and be recorded by an outside observer. The variation in the strength of the gravitational field near the horizon surface is strong enough to create pairs of particles and antiparticles spontaneously. The energy necessary to do this is extracted from the source of the gravitational field, and as the process continues, so the mass of the black hole ebbs away. If one waits long enough, it should disappear completely unless some unknown physics intervenes in the final stages. Such a discovery was exciting enough, but its most satisfying aspect was the fact that the particles radiated away from the surface of the black hole were found to have all the characteristics of heat radiation, with a temperature precisely equal to the gravitational field at the horizon and an entropy given by its surface area, just as the analogy had suggested. Black holes did possess a non-zero temperature and obeyed the laws of thermodynamics, but only when quantum mechanics was included in their description.

He saw two stars collapse against one another and a nova form; it flared up and then, as he watched, it began to die out. He saw it turn from a furiously blazing ring into a dim core of dead iron and then he saw it cool into darkness. More stars cooled with it; he saw the force of entropy, the method of the Destroyer of Forms, retract the stars into dull reddish coals and then into dust-like silence. A shroud of thermal energy hung uniformly over the world, over this strange and little world for which he had no love or use. It's dying, he realized. The universe. The thermal haze spread on and on until it became only a disturbance, nothing more; the sky glowed weakly with it and then flickered. Even the uniform thermal disbursement was expiring. How strange and goddamn awful, he thought. He got to his feet, moved a step toward the door. And there, on his feet, he died. They found him an hour later. Seth Morley stood with his wife at the far end of the knot of people jammed into the small room and said to himself, "to keep him from helping with the prayer". "The same force that shut down the transmitter," Ignatz Thugg said. "They knew; they knew if he phrased the prayer it would go through. Even without the relay." He looked gray and frightened. All of them did, Seth Morley noticed. Their faces, in the light of the room, had a leaden, stone-like cast. Like, he thought, thousand-year-old idols. Time, he thought, is shutting down around us. It is as if the future is gone, for all of us.

Perplexed about entropy? You are not alone. Josiah Willard Gibbs (1839–1903) understood this confusion all too well, almost 150 years ago, “ . . . a method involving the notion of entropy, the very existence of which depends upon the second law of thermodynamics, will doubtless seem to many far-fetched, and may repel beginners as obscure and difficult of comprehension. This inconvenience is perhaps more than counter-balanced by the advantages of a method which makes the second law of thermodynamics so prominent, and gives it so clear and elementary an expression. . . . (1).” Gibbs profoundly altered our understanding of chemistry with his insights. At a time when it was mostly a philosophical concept, Gibbs went straight for application and made entropy relevant. Rapid advancements and heralded achievements in the chemical sciences ensued. Enthalpy (H) is a measure of the internal energy of a system, but this energy has an availability issue; some of that energy is useful, some is not. Enthalpy also provides no information about the spontaneity of energy exchange. Entropy (S) does indicate the probability of energy exchange (i.e., spontaneous, −∆S, or nonspontaneous, +∆S), but it is not useful energy and so it provides little information on the quantity of energy that is available to perform work. Energy that is available to perform useful work is known as Gibbs energy, symbolized as G. Gibbs energy has also been termed free energy. Yet energy is anything but “free” and so that term will not be used here

This, in turn, has given us a “unified theory of aging” that brings the various strands of research into a single, coherent tapestry. Scientists now know what aging is. It is the accumulation of errors at the genetic and cellular level. These errors can build up in various ways. For example, metabolism creates free radicals and oxidation, which damage the delicate molecular machinery of our cells, causing them to age; errors can build up in the form of “junk” molecular debris accumulating inside and outside the cells. The buildup of these genetic errors is a by-product of the second law of thermodynamics: total entropy (that is, chaos) always increases. This is why rusting, rotting, decaying, etc., are universal features of life. The second law is inescapable. Everything, from the flowers in the field to our bodies and even the universe itself, is doomed to wither and die. But there is a small but important loophole in the second law that states total entropy always increases. This means that you can actually reduce entropy in one place and reverse aging, as long as you increase entropy somewhere else. So it’s possible to get younger, at the expense of wreaking havoc elsewhere. (This was alluded to in Oscar Wilde’s famous novel The Picture of Dorian Gray. Mr. Gray was mysteriously eternally young. But his secret was the painting of himself that aged horribly. So the total amount of aging still increased.) The principle of entropy can also be seen by looking behind a refrigerator. Inside the refrigerator, entropy decreases as the temperature drops. But to lower the entropy, you have to have a motor, which increases the heat generated behind the refrigerator, increasing the entropy outside the machine. That is why refrigerators are always hot in the back. As Nobel laureate Richard Feynman once said, “There is nothing in biology yet found that indicates the inevitability of death. This suggests to me that it is not at all inevitable and that it is only a matter of time before biologists discover what it is that is causing us the trouble and that this terrible universal disease or temporariness of the human’s body will be cured.

set aside more preserves, extinguished fewer species, saved the ozone layer, and peaked in their consumption of oil, farmland, timber, paper, cars, coal, and perhaps even carbon. For all their differences, the world’s nations came to a historic agreement on climate change, as they did in previous years on nuclear testing, proliferation, security, and disarmament. Nuclear weapons, since the extraordinary circumstances of the closing days of World War II, have not been used in the seventy-two years they have existed. Nuclear terrorism, in defiance of forty years of expert predictions, has never happened. The world’s nuclear stockpiles have been reduced by 85 percent, with more reductions to come, and testing has ceased (except by the tiny rogue regime in Pyongyang) and proliferation has frozen. The world’s two most pressing problems, then, though not yet solved, are solvable: practicable long-term agendas have been laid out for eliminating nuclear weapons and for mitigating climate change. For all the bleeding headlines, for all the crises, collapses, scandals, plagues, epidemics, and existential threats, these are accomplishments to savor. The Enlightenment is working: for two and a half centuries, people have used knowledge to enhance human flourishing. Scientists have exposed the workings of matter, life, and mind. Inventors have harnessed the laws of nature to defy entropy, and entrepreneurs have made their innovations affordable. Lawmakers have made people better off by discouraging acts that are individually beneficial but collectively harmful. Diplomats have done the same with nations. Scholars have perpetuated the treasury of knowledge and augmented the power of reason. Artists have expanded the circle of sympathy. Activists have pressured the powerful to overturn repressive measures, and their fellow citizens to change repressive norms. All these efforts have been channeled into institutions that have allowed us to circumvent the flaws of human nature and empower our better angels. At the same time . . . Seven hundred million people in the world today live in extreme poverty. In the regions where they are concentrated, life expectancy is less than 60, and almost a quarter of the people are undernourished.

A law in physics, called the second law of thermodynamics, says that entropy, or chaos (the opposite of growth…a winding-down process), increases over time. You can readily see this in life, and we have already talked about it. Anything left to its own is naturally dying, getting more disorganized, rusting, etc. Even the universe itself is subject to that process.

In human society, rich people can move faster by buying expensive cars and planes. However, physics recognises no such inequality. In physics, everyone — and every object — is equal. Everyone is treated the same. The laws of physics are the same for everyone. Everyone ages the same as entropy takes it toll equally. Under the laws of physics, everyone moves at the same speed in spacetime. You cannot buy a faster car to drive through spacetime more quickly. This is the true essence of the egalitarian Copernican principle. The world of physics is a more equal world.

It’s not clear why in the real world, the world made up of many particles, time only goes forward and entropy always increases,” Murch said. “But many people are working on that problem and I expect it will be solved in a few years,
